Load html scripts to kantu

Why it says [kantu] Cannot read property ‘data’ of undefined
I am launching Kantu with exported html files. This happens when program run first time. Second time it loaded the script to kantu so then it runs without any error.
process.StartInfo.Arguments = “/K” + @"""""" + @“C:\Program Files (x86)\Google\Chrome\Application\chrome.exe”" “”" + ScriptFolder + testScript + “?direct=1&close=1&savelog=” + logName + ‘"’;
